Yes, on MIPS, it would use DTPREL: "R_MIPS_TLS_DTPREL32 and R_MIPS_TLS_DTPREL64, originally only resolved by the dynamic linker, were reused as static relocations as well for use in debug information." (see http://www.linux-mips.org/wiki/NPTL ) From what I can tell this also applies to TPREL. As far as I can tell, this is MIPS-specific but also shouldn't break other archs, so the patch previously submitted by Vincent Wen adequately solves this problem (see http://lists.uclibc.org/pipermail/uclibc/2013-March/047701.html ). However, the commit comment doesn't explain why it solves the problem, so I'll submitting a patch shortly with an improved explanation.
